Gord Downie leaving 'a much greater mark than just music,' his doctor says

It hasn't been easy treating GordDownie on tour this summer, hisneuro-oncologistsays,but he's impressed by his ability to handle the illness and still put on such gripping performances.

"From what I hear, from what I've seen, it's absolutely electric,"said Dr. James Perry, head of neurology at Sunnybrook Health Sciences Centre."It's emotional. There's not a dry eye in the house, especially during certain songsand he seems to be managing it amazingly well."

In December,Downiewas diagnosedwith glioblastoma,an aggressive, incurable form of brain cancer. Following the diagnosis,he vowed to join his bandmates of more than 30 yearson theirsummer tour in support of their new albumMan Machine Poem.

'So much joy'

"It's been an interesting thing to watch so far,"Perry said. "There have been no issues medically. He's done, and they've done, better than I could have possibly imagined and the crowds are evidence of that. There's just so much joy."

As for managing his time at SunnybrookHospitalas well as treating Downie on tour, Perry said it has been hectic.

"It's a challenge," he said. "You know what they say, if you want something done, give it to somebody busy.I'll look forward to a break in a couple of weeks."

Perry said it's too soon to say which memory will be his favouritebecausethe tour is just halfway done. Butthere are many positive things that stand out.

"It's going to be the hope that will be provided for my patients and patients across Canada that are going tobenefit from his courage," he said. "The hope and awareness he's bringingand the unprecedented amount of money that will be focused on this type of tumour."

'A greater mark than just his music'

In the past, it has been difficult to raisefunds for glioblastoma, a relatively unknown and less common type of cancer that desperately needs research funding for new therapies, according to Perry.

"Everybody's talking about Gord and about the efforts to raise money. It's just a heart-wrenching revelation for most people," he said. "It's not about me, it's about our patients and it's about him. It's about his ability to leave a much greater mark than just his music. This is going to be a transformational amount of money."

Following the tour, the band will get together with Sunnybrook Hospital and decide how to direct the money donated to the hospital's Gord Downie Fund for Brain Cancer Research.The money will likely be used to acquire more brain tumour research space and build more facilities at Sunnybrook Hospital for treatment.

Perry said he can'tprovidean update onDownie'scondition but for fans who want to know how he is, the energy he presents onstage is evidence enough.

"If youwant to know how he's doing, go to a show orwatchYouTubeclips from the shows that have gone on and you'llsee him dancing. He's singing amazingly well. His pitch is great and he's having the time of his life."
